CHAPTER 4: RECOVERY
4.1. Helpful Hints for Recovering R-410A
R-410A has been designated by the EPA as a “very-high-pressure” refrigerant. Because of its higher
vapor pressure, recovering R-410A has some unique challenges. The higher vapor pressure requires
more work from the compressor, resulting in higher temperatures and increased wear on moving
compressor parts.
In order to reduce the affects of these conditions, Bacharach recommends the following:
• Whenever possible, cool your recovery tank with ice or water. This keeps the compressor
discharge pressures lower, which will result in faster recovery rates and longer compressor
life.
• Avoid recovering large amounts of R-410A at one time. Allow the recovery unit and cylinder
to cool before starting the next recovery job.
• Always purge the machine completely when switching from R410a and back to prevent cross
contamination.
Following these simple hints will improve both recovery performance and compressor life.
4.2. Vapor/Liquid Recovery Procedures
Step Description
1 Turn off all electrical or mechanical power to the refrigerant device to be evacuated.
2
Make proper hose connections: Connect refrigerant hoses to recovery cylinder, the unit,
and A/C system as shown in Figure 1. NOTE: You must use an external filter drier in the
suction line in order to meet the conditions of the unit warranty. Caution: If the 80% shutoff
cord is not used, a scale must be used to monitor the refrigerant level in the recovery
cylinder.
NOTE: Although the 3600 was designed to handle liquid slugging, pumping large amounts of
liquid over extended periods of time will reduce the life of the compressor. If large amounts of
liquid are present, it is recommended that you use the liquid push - pull method of recovery
prior to vapor recovery operations. (See Figures 3 & 4).
3
Place the inlet and purge ball valves in the “CLOSED” position and the outlet valve is in
the “OPEN” position. Open the DOT recovery tank liquid valve. (See Figure 2).
4
Turn the system switch to the “ON” position. The LED status display will be green.
5
Regulate the inlet port ball valve when liquid refrigerant is present.
WARNING: A “knocking” sound coming from the compressor indicates too much liquid is
entering the compressor. The inlet ball valve must be regulated as shown in the
shaded region until this knocking sound stops, otherwise compressor damage
could occur. Pumping liquid when the compressor is knocking will damage the
compressor and will reduce the compressor life and will void the compressor
warranty.

Step Description
6
Monitor the LED status display. The unit will shut off automatically when the proper vacuum
level is achieved and the status display LED will turn off.
LED Description
Green
Indicates that the power switch is ON and the compressor is running.
If the green LED is off, this indicates that the unit has shut down because
the system being evacuated has reached 13" HG. (the evacuation is
complete). Check the suction pressure to verify that the system being
evacuated is down to at least 13" HG vacuum. Turn the system switch
to the OFF position. Wait 5 minutes. If the inlet pressure rises above 0
psig. Repeat steps 3-6. If the inlet pressure remains below 0 psig, close
all valves and disconnect the hose from the A/C system.
NOTE: A small amount of inlet pressure may be needed to reset the
vacuum switch, this is normal.
Red
(a) Indicates that there is a high-pressure condition that must be
corrected. Check for restrictions or a full recovery tank. Correct
the problem and turn the system switch OFF to reset the system.
Repeat steps 3-6.
(b) Indicates that the recovery tank is full (if the 80% automatic shutoff
option is installed). Change the recovery tank and repeat steps
3-6.
7
Purge the system by positioning the inlet and purge ball valve in the “PURGE” position
(both pointing DOWN). This should be done with the unit off. If the valves are turned while
the unit is running, the system may shut off either on high-pressure or vacuum. If the unit is
manually or automatically turned off before the evacuation is complete, repeat steps 3-7.
NOTE: If the circuit breaker trips, wait 5 seconds, reset circuit breaker and go to step 3. If
the compressor thermal overload trips, wait 16 to 30 minutes before restarting.

4.4. Liquid Push-Pull Recovery General Information
Attention: Before attempting the following liquid push-pull recovery operations, please review this page.
It may not be possible to recover liquid refrigerant from some types of refrigeration equipment.
A scale or liquid sight glass can be used to determine when all the liquid is recovered. The unit will not pull
a vacuum using the push-pull liquid recovery operation. To finish the recovery operation, you must
proceed to vapor recovery operations.
Guidelines
If any of these conditions are present in the system being evacuated, liquid push-pull operations may not
be practical and vapor recovery operations should be performed.
• The equipment contains less than 15 lbs. of refrigerant.
• The equipment is a heat pump or other system with refrigerant flow that would prevent you from
isolating the liquid.
• Equipment has an accumulator between the service ports used in the liquid recovery process.
• Liquid refrigerant migration has occurred and the location of the liquid is unknown.
• The refrigerant tubing design on the equipment does not allow for a solid column of liquid refrigerant
to be formed.
Direct Liquid Recovery Operations
All compressors are designed to compress gases. Normally compressors are not capable of pumping
non-compressible fluids such as liquid refrigerant, however, the 3600 has been designed with a special
head and valves that enable it to handle liquid directly. This feature makes the 3600 easier to use by
minimizing the need to monitor incoming refrigerant vapors and reduces compressor failures due to liquid
slugging.
It is important to remember that the 3600 is a compressor and not a liquid pump. When large amounts of
liquid are present, the liquid push-pull method of recovery should be used. Using the 3600 to pump large
amounts of liquid refrigerant over a long period of time will reduce the compressor life.
WARNING: A “Knocking” sound coming from the compressor indicates too much liquid is entering the
compressor. The inlet ball valve must be regulated as shown in the shaded region until this
knocking sound stops, otherwise compressor damage could occur. Pumping liquid when the
compressor is knocking will damage the compressor and will reduce the compressor life.
This will void the compressor warranty
.
A sudden slug of liquid into the compressor may cause a sudden spike in pressure and cause the high-
pressure safety shutoff switch to shut the compressor off. If this happens, you must clear the liquid from
the compressor before you can restart the compressor. To prevent this from happening, always open the
inlet valve slowly when starting a recovery job. Opening the inlet valve quickly could allow a slug of liquid
to enter the cylinder and cause the high-pressure switch to shut the system down.
Model 3600 Refrigerant Recovery System

4.5. Liquid Push Pull Recovery Procedures
Liquid push-pull operations are performed by using hot compressor gas to push liquid refrigerant out
of a system. The purge valve accomplishes this by re-directing the hot compressor gas around the
condenser. See the diagram on top of the unit for hose connections.
Step Description
1
Turn off all electrical or mechanical power to the refrigerant device to be evacuated.
2
Make proper hose connections. Connect the discharge hose from the outlet port to the low-
pressure side of the system you are servicing. Connect a hose between the liquid port
(receiver or condenser) on the system being serviced and the liquid valve on the DOT
recovery tank. Connect the inlet hose from the DOT recovery tank vapor valve and the unit’s
inlet port. See Figure 3 for hose connection schematic. NOTE: You must use an external
filter drier in the suction line in order to meet the conditions of the unit warranty. Caution: If the
80% shutoff cord is not used, a scale must be used to monitor the refrigerant level in the
recovery cylinder.
3
Place the inlet and purge valves in the “LIQUID PUSH-PULL” position. This will allow hot
compressor gas to bypass the condenser. OPEN the liquid and vapor valves on the tank,
(See Figure 4)
4
Open the outlet ball valve and the DOT recovery tank vapor and liquid valves on the
DOT recovery tank.
5
Turn the system switch to the “ON” position. When all liquid refrigerant is recovered, turn
the system switch to the “OFF” position. NOTE: Liquid push-pull operations do not pull a
vacuum on a system. You must perform a vapor recovery operation in order to pull the system
down to the required vacuum level.
6
Monitor the LED status display.
LED Description
Green
SYSTEM ON: The “SYSTEM ON” indicator should be ON during normal
operations.
No LED
EVACUATION COMPLETE: Indicates that the unit has shut down because
the system being evacuated has reached 13" HG. (the evacuation is
complete). During liquid push-pull operations the system will not be pulled
into a vacuum. NOTE: A small amount of inlet pressure might be needed
to reset the vacuum switch, this is normal.
Red
HIGH PRESSURE: Indicates that there is a high pressure condition that
must be corrected. Check for restrictions or a full recovery cylinder. Correct
problem and turn system switch to the OFF position. Repeat steps 3-6.
TANK FULL: Indicates that the recovery cylinder is full (if the 80%
Automatic Tank Full Shutoff Option is installed). Change the recovery
cylinder and repeat steps 3-6.
7
Turn the system switch to the OFF position when all liquid is recovered. The liquid
recovery operation is complete when the scale or optional sight glass indicates no liquid is
being transferred to the recovery cylinder. NOTE: The unit must be manually shut off during
all liquid recovery operations.
8
Proceed to vapor recovery operations to complete the recovery operation. If the unit is
manually or automatically turned off before the liquid recovery is complete, repeat steps 3-8.
NOTE: If the circuit breaker trips, wait 10 seconds, reset circuit breaker and go to step 2. If
the compressor thermal overload trips, wait 16 to 30 minutes before restarting.

4.7. Pump Down Operations
The Model 3600 is equipped with a pump-down purge valve that allows the technician to pump down or
evacuate the 3600 before proceeding to the next recovery operation. This procedure not only eliminates
cross contamination, but also conserves refrigerant. Follow the steps below to ensure your pump down
operation is performed correctly.
Step Description
1 After recovery operations are complete and the system switch is in the OFF position:
FIRST - Place the inlet valve in the PURGE position
SECOND - Place the purge valve in the PURGE position
THIRD - Place the outlet valve in the OPEN position as illustrated below.
It is important to turn the valves in this order to ensure the compressor properly
equalizes.
2 Turn the system switch to the “ON” position. The LED status will be green.
NOTE: If the compressor fails to start, cycle the purge valve from the RECOVERY to PURGE
position to reduce the pressure difference shown on the system’s gauges.
3 Allow the unit to run until it shuts off automatically. The status display will flash “EVACUATION
COMPLETE” indicating that the purge operation is complete.
4 Turn the system switch to the OFF position and turn the outlet valve to the “CLOSE”
position. Close the inlet and outlet valves on the DOT recovery tank.
During the pump down operation, the 3600’s compressor pulls the entire system and discharge hose into
a vacuum and discharges the gas directly out of the discharge port leaving no more than ¼ ounce of
refrigerant left in the system.
CAUTION! Never turn the purge valve when the unit is operating! Severe damage may occur.

4.8. DOT Recovery Cylinder Safety
An optional 80% recovery cylinder shutoff cord is available with the Model 3600. If equipped, this cord
connects to the recovery cylinder float switch and will automatically shut the Model 3600 off when the
recovery cylinder becomes 80% full.
When the Model 3600 is equipped with the 80% shutoff cord, Bacharach recommends that you use this
cord for added safety. If the Model 3600 is not equipped with an 80% shutoff cord, or, if you are using a
recovery cylinder that does not have a float switch, then you must use a scale and the guidelines below to
prevent overfilling of the cylinder.
N
OTE: THE SHORTING CAP MUST BE USED IN ORDER TO OPERATE THE MODEL 3600 WITHOUT THE 80% SHUTOFF
CORD ATTACHED TO THE RECOVERY CYLINDER
.
Bacharach uses and recommends the Air Conditioning & Refrigeration Institute's (AHRI) guideline K for
the safe filling and handling of used refrigerant. This Publication is available from ARI.
WARNING: You must use a DOT recovery cylinder approved for use with R-410A refrigerant.
This recovery system is equipped with a high-pressure shutoff switch set to turn the
unit off at 550 psi. Using any other cylinder may cause the pressure in the recovery
cylinder to exceed the cylinder’s pressure rating.
The following information provides the safe fill weights for used refrigerant based on the size of the
container and is in accordance with Guideline K.
